Data are a critical tool for understanding how COVID-19 is impacting our community. The Onondaga County Health Department is actively tracking cases in Onondaga County to identify trends as well as demographic and geographic variations in transmission and outcomes. The data presented on this webpage represent laboratory-confirmed cases of COVID-19. Many people with COVID-19 do not undergo testing, therefore these data represent only a portion of the total number of people in Onondaga County with COVID-19 infections.

Please note all data presented are preliminary and subject to change as case investigations are completed or more information becomes available. Information that is not yet known or was not provided during the course of a case investigation will be marked as “unknown.” The data are organized into the following sections:

This section displays trends relating to cases of COVID-19 in Onondaga County. Unless otherwise specified, trend graphs use week of onset to track cases over time. The unit of measurement used is MMWR week, the standard unit of measurement used by the Centers of Disease Control. In instances where onset date is not known, such as for cases that do not experience any symptoms, collection date is used in place of onset date. If both onset date and collection date are unknown, laboratory receipt date is used.

Testing in Other Community Sectors
In order to monitor the impact of resuming in-person instruction, several local colleges and universities have undertaken pooled testing of their students, faculty, and staff populations. These testing approaches differ from diagnostic testing performed within the general Onondaga County community. Please note any individuals who test positive for COVID-19 through pooled testing undergo diagnostic testing, when appropriate, and are included in Onondaga County’s COVID-19 case counts if they are an Onondaga County resident or were on campus at the time of the onset of their symptoms.

Syracuse University maintains a dashboard of counts of tests conducted within their student and employee populations. The Syracuse University dashboard can be viewed at

  • Travel: Cases among individuals who have traveled outside of central New York and have no other known exposures.
  • Senior Facility: Residents and staff of a nursing home, assisted living facility, or senior apartment complex who were likely exposed to a positive case within the facility. Individuals with known exposures outside of the facility are not included in this category.
  • Unknown: Cases for whom the exposure type is not yet known. Exposure types are updated whenever new information becomes available.
